WASHINGTON — President Donald Trump once presided over a reality show in which a key cast member exited each week. The same thing seems to be happening in his White House.

Trump's West Wing has descended into a period of unparalleled tumult amid a wave of staff departures, yet the president insists it's a place of "no Chaos, only great Energy!" The latest to announce his exit is Gary Cohn, Trump's chief economic adviser, who had clashed with the boss over trade policy.
